Imagenes por resonancia mágnetica de la articulación temporomandibular / Images for magnetic resonance of the temporomandibular joint

ABSTRACT

The term temporomandibular disorder embraces a number of clinical problems that involve the masticatory musculature, the temporomandibular joint (TMJ) and its associated structures, or both. The most common intra-articular abnormality of the TMJ is internal deragement, which is defined as an abnormal relationship of the articular disk to the mandibular condyle and the articular tubercle. Magnetic resonance imaging is considered the optimum modality for imaging the TMJ in patients with temporomandibular disorders, because could demonstrate fine anatomic details and pathologic changes and provide valuable information for determining the type and stage of joint abnormality. This article consists of a revision of the subject, accompanied by some selected images of made studies in the Centro de Imagenología, Hospital Clínico Universidad de Chile.
